Abstract
Objective The purpose of this study was to assess the safety of transgenic maize CC-2 through a 90-day feeding study in Sprague-Dawley rats. Methods Transgenic maize CC-2 and its parental counterpart maize Zhengdan 958 were respectively incorporated into diets at levels of 70%, 35% or 17.5% (w/w) and were administrated to rats (n = 10/sex/group) for 90 days. An additional control group of rats (n = 10/sex/group) were fed with the AIN93 breeding diet. All formulated diets were nutritionally balanced. Results There was no death and obvious toxic symptom in all rats. Food consumption, body weight, total food consumption rate, hematology, urinalysis, organ weight and organ coefficient were comparable between transgenic groups and the corresponding dose parental groups. There were significant differences of food consumption rate on some timepoint between high dose transgenic group and high dose parental group; male rats in high dose transgenic group showed significantly higher ALT/AST than high dose parental group on the middle or end of the experiment; but the differences showed no biological significance. There were no significant differences of other serum biochemistry parameters and pathological changes. Conclusion The results in this study demonstrated that the transgenic maize CC-2 didn't cause any related toxicity in rats.

Abstract
Neddylation plays a vital role in post-translational modification, intricately shaping the regulation of diverse biological processes, including those related to cellular immune responses. In fact, neddylation exerts control over both innate and adaptive immune systems via various mechanisms. Specifically, neddylation influences the function and survival of innate immune cells, activation of pattern recognition receptors and GMP-AMP synthase-stimulator of interferon genes pathways, as well as the release of various cytokines in innate immune reactions. Moreover, neddylation also governs the function and survival of antigen-presenting cells, which are crucial for initiating adaptive immune reactions. In addition, neddylation regulates T cell activation, proliferation, differentiation, survival, and their effector functions, thereby ensuring an appropriate adaptive immune response. In this review, we summarize the most recent findings in these aspects and delve into the connection between dysregulated neddylation events and immunological disorders, especially inflammatory diseases. Lastly, we propose future directions and potential treatments for these diseases by targeting neddylation.

Abstract
OBJECTIVE To investigate the repairing effect of Lactobacillus acidophilus LA11-Only on ceftriaxone induced intestinal micronbiota imbalance in mice and its alleviating effect on lipid metabolism. METHODS A total of 30 SPF BALB/c male mice were randomly divided into control group(10) and model group(20). The model group was given ceftriaxone sodium solution by gavage for a week to create a mouse model of antibiotic flora disorder. The natural recovery group(10) was given 10% skimmed milk solution by gavage, and the LA11-Onlly group was given Lactobacillus acidophilus skimmed milk solution(1.0×10~9CFU/mL). Two weeks later, the feces were collected aseptically.16S rRNA sequencing technology and ultra-high-performance liquid chromatography combined with mass spectrometry(UPLC-MS) were used to analyze the repair effect of LA11-Onlly on antibiotic induced bacterial flora disorder and lipid metabolism in mice. RESULTS After ceftriaxone treatment, the diversity of intestinal microbiota in mice decreased, and there was a significant difference in the composition of flora compared with the control group; After treatment with LA11-Onlly, the Alpha diversity increased, the abundance of beneficial bacteria such as Lactobacillus and Butyricicoccus increased, and the composition of flora was closer to the control group; At the same time, the concentration of short chain fatty acids(SCFAs) increased in varying degrees. Compared with the natural recovery group, the levels of butyric acid and valeric acid in LA11-Onlly group increased significantly, close to the same level as the control group. CONCLUSION Lactobacillus acidophilus LA11-Onlly probiotics can inhibit the growth of harmful bacteria by regulating the diversity and community composition of intestinal microbiota, promote the increase of the concentration of SCFAs, and alleviate the damage of antibiotics to the body.

Abstract
OBJECTIVE To develop a prediction equation for estimation physical activity level(PAL) based on the average daily steps in Chinese adults and to verify its prediction power. METHODS A total of 800 adults with no restriction on physical activity were recruited. Excluding those who wore Actigragh WGT3X-BT accelerometer continuously for less than 3 days, 743 subjects(324 males, 419 females, mean age 31.4 years) were finally included. Daily steps, time of low intensity physical activity(LPA), moderate physical activity(MPA) and vigorous physical activity(VPA) and physical activity energy expenditure(PAEE) were measured by the accelerometer. The method of external validation was adopted. The measured PAL calculated by basal metabolic rate(BMR) measured by indirect thermography(IC) and total energy expenditure(TEE) measured by doubly labeled water method was used as the gold standard. The consistency of the prediction formula was verified by Bland-Altman analysis and the accuracy was verified by the accurate. RESULTS The prediction equation was developed: PAL=1.17 + 0.000028 Steps. In the external verification, the mean difference was 0.05, the 95% consistency limit was(-0.26, 0.36), and the accuracy was 73%, indicating a good consistency. CONCLUSION The prediction formula of PAL for Chinese adults based on the steps has good performance and can be applied to the management of physical activity and the prevention of obesity in Chinese adults.

Abstract
The association between physical activity (PA) and dyslipidemia is well known, but the relationship between a temporal pattern of PA and dyslipidemia remain unknown. Here, we aimed to identify the intensity and temporal patterns of PA clustered by the trajectory model and their relationship with dyslipidemia. The participants were 701 adults (305 males) aged 18−60 years undergoing continuous measurement of PA with Actigraph GT3X+ accelerometers for at least 3 days. A trajectory analysis was applied based on moderate-to-vigorous intensity physical activity (MVPA) accumulated values over every period per day. The association between PA and dyslipidemia was estimated using a logistic regression model. Four distinct PA trajectory groups in the population were identified (continued low, stable and moderate, late increasing, and early increasing). Specifically, the “moderate and stable group” was associated with a decreased rate of high TG (p < 0.05) and the “moderate and stable group” and “late increasing group” were associated with decreased rates of low HDL-C (p < 0.05). In conclusion, there were four activity trajectory groups in this population and the continued low PA trajectory was associated with a high prevalent rate of an abnormal lipid profile, and continued and moderate activity or late afternoon increasing activity might have lower HDL-C distribution.

Abstract
Cracks in a tunnel lining often emerge under the coupling action of earth and water pressures in a complex stratum environment, and accidents often occur in the process of repairing cracks. In this study, we used the force-sensitive properties of embedded carbon fibre to conduct early-warning research on lining reinforcement to prevent secondary damage during tunnel lining reinforcement. According to the earth load characteristics, a bond stress–slip model of the embedded carbon fibre under bidirectional earth pressure was established on the basis of the thick-walled cylinder theory and the semi-inverse method in elastic theory. The length change of a single fibre was obtained on the basis of the principle that the volume of a single carbon fibre is constant during the deformation process. The resistance and strain model of the single carbon fibre under the action of an external force was then established following the relationship between the resistance, the length change and the volume change of the single carbon fibre. The resistance of carbon fibre composite materials, according to their production technology and unidirectional force properties, was assumed to be a mixture of the series and parallel resistances of the single carbon fibre, and a piezoresistive model of carbon fibre composite materials was formed by using the multidimensional Taylor series expansion and the idea of the average equivalent. The comparison between the theoretical and monitoring values of the piezoresistive model in a tunnel project in Tibet, China revealed that the resistance of various types of carbon fibres increases with the radius of the lining reinforcement and earth pressure and decreases with an increase in the lining reinforcement thickness. Meanwhile, the angles at different positions of the lining reinforcement also have certain effects on the resistance value of the carbon fibre. The variation curve of the piezoresistive model was exponential in both deeply and shallowly buried tunnels, which verifies the rationality of the model.

Abstract
The type of diet is very important for the maintenance of health and nutrition. How the sole source of carbohydrates from rice- or flour-based diet affect blood sugar has not been elucidated for a long time. In order to explore the effects of these diets, sixty SD rats were randomly divided into three groups: control group (C group, AIN-93, standard diet), rice diet group (R group), and flour diet group (F group). All the rats were fed for 7 weeks in total by the assigned diets for 4 weeks (stage 1, S1) and all by the AIN-93 diet for 3 weeks (stage 2, S2). The body weights of all the rats were monitored and serum samples were taken for testing blood glucose, biochemical indicators and untargeted lipidome. It was found that both rice and flour-based diets caused weight gain, but the flour diet had a significant increase in blood sugar and low-density lipoprotein (LDL), while a significant decrease in albumin (ALB) and triglycerides (TG). Twenty-three and 148 lipids were changed by lipidomics in the rice diet group and flour diet group, respectively, and two lipids showed the same changes in the two groups, all belonging to TGs, namely TG (16:0/16:0/16:1) and TG (16:0/16:1/18:2), which showed that a single diet source had a significant effect on the health of rats. Fortunately, we can recover this effect through the subsequent standard diet, allowing the rats to return to normal blood sugar, weight and biochemical indicators. A model can predict the diet types through the logistic regression method. Finally, we proposed that a single diet increased blood sugar and weight through a decrease in TGs, and blood sugar and weight returned to normal after a standard diet. Taken together, the short-term negative effects caused by a single diet can be recovered by a standard diet and further proves the importance of diet types.

Abstract
OBJECTIVE To investigate the effects of rice on intestinal microflora in rats. METHODS Thirty 4-week-old male SD rats were randomly divided into control group, rice group and wheat group according to body weight. The control group was fed with AIN-93 diet, the rice group and the wheat group was fed with the AIN-93 diet which the carbohydrate was replaced with rice and wheat, respectively, for 4 weeks. At the end of the experiment, lipid related biochemical indexes were determined, and the contents of the distal colon(feces) of rats were collected for macro factor detection. RESULTS From the beginning to the end of feeding, there was no difference in weight gain among the groups. After the end of the experiment, there was no difference among lipid-related indicators and blood glucose. α diversity showed that there was no difference in the diversity of intestinal microbiota between the rice and wheat groups, and the gene abundance analysis of intestinal microbiota in the wheat group showed that the gene abundance of intestinal microbiota was lower. The difference analysis of intestinal microbiota result showed that compared with the rice group, the wheat group was composed of higher proportion of verrucomicrophyla and lower proportion of Bacteroidetes. Lefse analysis showed that the surface group was enriched with Akkermansia Muciniphila, Bifidobacterium animalis, and a variety of beneficial bacteria such as Faecalibaculum rodentium and Intestinimonas butyriciproducens, while Prevotella copri was rich in the rice group. Glycoside hydrolases 8, glycoside hydrolases 16, glycoside hydrolases 99 and glycosyl transferase family 56. CONCLUSION Rice or wheat as different carbohydrate sources have different effects on the composition of intestinal microflora and carbohydrate-related active enzymes in rats.

Abstract
Bird feathers are the product of interactions between natural and artificial selection. Feather-related traits are important for chicken selection and breeding. Frizzle feather is characterized by the abnormally development of feathers in chickens. In the current study, frizzle feather characteristics were observed in a local breed called Xiushui Yellow Chicken in Jiangxi, China. To determine the molecular mechanisms that underlie frizzle feather in Xiushui Yellow Chicken, four populations of three breeds (Xiushui Yellow Chicken with frizzle feathers, Xiushui Yellow Chicken with normal feathers, Guangfeng White-Ear Yellow Chicken, and Ningdu Yellow Chicken) were selected for whole-genome resequencing. Using a comparative genome strategy and genome-wide association study, a missense mutation (g.5281494A>G) and a 15-bp deletion (g.5285437-5285451delGATGCCGGCAGGACG) in KRT75L4 were identified as candidate mutations associated with frizzle feather in Xiushui Yellow Chicken. Based on genotyping performed in a large Xiushui Yellow Chicken population, the g.5285437-5285451delGATGCCGGCAGGACG mutation in KRT75L4 was confirmed as the putative causative mutation of frizzle feather. These results deepen the understanding of the molecular mechanisms responsible for frizzle feather, as well as facilitating the molecular detection and selection of the feather phenotype in Xiushui Yellow Chickens.

Abstract
Liver Sinusoidal Endothelial Cells (LSEC) line the hepatic vasculature providing blood filtration via transmembrane nanopores called fenestrations. These structures are 50-300 nm in diameter, which is below the resolution limit of a conventional light microscopy. To date, there is no standardized method of fenestration image analysis. With this study, we provide and compare three different approaches: manual measurements, a semi-automatic (threshold-based) method, and an automatic method based on user-friendly open source machine learning software. Images were obtained using three super resolution techniques - atomic force microscopy (AFM), scanning electron microscopy (SEM), and structured illumination microscopy (SIM). Parameters describing fenestrations such as diameter, area, roundness, frequency, and porosity were measured. Finally, we studied the user bias by comparison of the data obtained by five different users applying provided analysis methods.

Abstract
BACKGROUND Data from the 2010-2012 Chinese National Nutrition and Health Survey showed that the vast majority of postmenopausal women in China had dual deficiencies in calcium and estrogen. OBJECTIVE This study aimed to clarify whether calcium supplementation alleviated bone loss caused by calcium restriction combined with estrogen deficiency in rats. METHODS Forty-eight female rats aged 9 weeks were assigned to 4 groups and fed a low-calcium diet: sham-operated (SHAM-LC), ovariectomized (OVX-LC), and ovariectomized rats treated with 750 mg/kg (OVX-LC-M) or 2800 mg/kg CaCO3 (OVX-LC-H). CaCO3 or distilled water was administered orally for 13 weeks. Bone mineral density (BMD) and histomorphometry of the femur, serum biochemical parameters, and serum metabolites were analyzed. RESULTS The OVX-LC rats showed a significant increase in body weight and serum levels of lipid markers, a significant decrease in serum estradiol, calcium, phosphorus, and 25(OH)D levels, and deterioration of the femur. At 750 mg/kg and 2800 mg/kg, CaCO3 reduced the deterioration of trabecular bone and increased the trabecular area percentage (Tb.Ar %) and BMD of the femur. Serum estradiol levels increased in a dose-dependent manner after CaCO3 supplementation (p < 0.01). The administration of 2800 mg/kg CaCO3 decreased serum triglyceride and high-density lipoprotein levels (p < 0.05) and decreased the levels of the bone turnover markers osteocalcin, N-telopeptide of type I collagen and β-crosslaps. The results of the metabolomics analysis showed that the glycerophospholipid metabolism pathway was closely related to calcium supplementation, and more DG (44:6 n3), LysoPC (22:2) and PE (P-34:3) and less Cer (d43:0) and PE-NMe2 (46:3) were produced. CONCLUSIONS The results clearly indicated that calcium supplementation was beneficial for decreasing bone loss in OVX-LC rats. The present study is the first to show that calcium supplementation increased the estradiol content in OVX-LC rats, and the effect of calcium on bone loss may be partially attributed to the increase in the estrogen level that subsequently induced the changes in metabolite levels, eventually increasing the bone mineral density to a relatively higher level to reduce bone deterioration.

Abstract
The primary cilium, a sensory organelle that protrudes from the surface of most eukaryotic cells, receives and transduces various critical signals that are essential for normal development and homeostasis. Structural or functional disruption of primary cilia causes a number of human diseases, including cancer. Primary cilia has cross talks with cell cycle and it may act as a cell cycle checkpoint to suppress cancer development. Moreover, primary cilia has cross-regulation with autophagy, which may affect tumor progression. We then discuss the association of the primary cilia with several oncogenic signaling pathways, including Shh, Wnt, Notch and platelet-derived growth factor receptor (PDGFR). Since these signaling pathways are often over-activated in many types of human cancers, primary cilia are likely to play a role in the tumorigenesis by modulating these pathways. Finally, we summarize current progress on the role of cilia during tumorigenesis and the challenges that the cilia-cancer field faces.

Abstract
OBJECTIVE Based on the accelerometer, the validity of the international physical activity questionnaire long version(IPAQ-L) and Bouchard diary were evaluated to measure the daily physical activity of Chinese adults aged 18-59 years old. METHODS A total of 200 Chinese adults were recruited in Yinzhou District of Ningbo City in 2019, including 78 males and 122 females, the three age groups 18-29, 30-49, 50 and above accounted for 19. 5%, 61. 5% and 18. 0%, respectively. The volunteers wore Actigraph WGT3 x-BT three-dimensional accelerometer for 3 days, and completed the 3 consecutive days& apos; Bouchard diary and the IPAQ-L. The physical activity energy expenditure(PAEE), sedentary inactivity time, light physical activity time(LPA) and moderate-to-vigorous physical activity time(MVPA) measured by the three tools were estimated respectively. Spearman analysis was used to analyze the correlation, the Friedman test and the Bland-Altman plot were used to test the homogeneity of the three method. RESULTS 196 volunteers were included in this study. The correlation coefficients of PAEE between IPAQ and diary and accelerometer were 0. 32 and 0. 58, respectively, the correlation coefficients of sedentary behavior were 0. 17, 0. 25, and LPA time was 0. 33, and the estimated IPAQ for MVPA time better than diary. The difference test result showed that, except for IPAQ in the measurement of MVPA, there was no statistical difference from the accelerometer measurement result(P=0. 684), and the difference between other estimated values and the accelerometer measurement result was statistically significant(P& lt; 0. 01), Bland-Altman plot result showed that the diary and IPAQ had good consistency in the measurement of PAEE and IPAQ in the estimation of MVPA time, but there was an overestimation in PAEE. In addition, IPAQ had poor validity in measuring sedentary behavior and LPA. CONCLUSION IPAQ and Bouchard diary have better validity in evaluating PAEE, and the diary is better than IPAQ. IPAQ has better validity in evaluating MVPA time, but has poor validity in estimating sedentary behavior and LPA time.

Abstract
OBJECTIVE To study the effect of calcium content on bone mineral density and intestinal microbiota in ovariectomized rats. METHODS A total of 30 Wistar rats were randomly divided into 3 groups, namely the sham operation group, the model group and the calcium carbonate supplement group. Postmenopausal osteoporosis rats were established by ovariectomy(OVX). After the first week of modeling, each group was intragastric separately. The calcium carbonate solution was given to the calcium carbonate supplement group, and the same amount of sterile water was given to the other two groups. The animals were executed at the end of the 12 weeks. Left femur was taken and bone mineral density(BMD) was detected by dual-energy X-ray absorptiometry. The total DNA of fecal samples was aseptically extracted and the Illumina Miseq platform was to carry out high-throughput sequencing. RESULTS Compared with the sham operation group, the body mass increment of rats in the model group was significantly increased, the level of BMD was significantly reduced(P<0. 05), the intestinal microbiota diversity was not significantly changed, the Firmicutes abundance was decreased, and the Bacteroidetes abundance was increased. Compared with the model group, the body mass increment of rats in the calcium carbonate supplementation group was significantly reduced and BMD was significantly increased(P<0. 05). There was no significant change in the intestinal microbiota diversity, Firmicutes were increased, and Bacteroidetes were decreased. CONCLUSION Calcium supplementation can improve bone mineral density and inhibit the increase of body mass during the experiment period, and its mechanism may be related to regulating the structure of intestinal microbiota.

Abstract
OBJECTIVE To compare the result of serum folate determined by improved microbial assay and electrochemiluminescence method, and to look for the relationship between them, so as to provide basis for the assessment of nutrition status of folate in population. METHODS A total of 258 serum samples were examined by improved microbial assay and electrochemiluminescence method. The correlation and consistence of the two method were analyzed. RESULTS The result showed that the correlation coefficient of the two method was 0. 885, which indicated that the result of two method were highly correlated. Results of Bland-Altman method showed that 94. 5% of the values were within the consistency limit, and the Kappa value of Kappa test was 0. 665. The result of consistency analysis showed that there were some differences between the two methods, and the result of serum folate tested by improved microbial assay were higher than that of electrochemiluminescence method in general. CONCLUSION The result of serum folate tested by electrochemiluminescence were highly correlated with the improved microbial assay, yet there are some differences in the consistency result between the two methods. Evaluating the nutrition status of folate by electrochemiluminescence may lead to a higher number of folate deficiency.

Abstract
The genetically modified maize carrying an insect-resistant gene and herbicide-tolerant gene has substantial benefits for crop production. The three-generation reproductive toxicity of the maize was studied in this paper. One hundred and eighty Sprague-Dawley (SD) rats were divided into three groups, which were fed with a genetically modified maize (GM) diet, receptor maize (RM) diet, and AIN-93G (AIN) diet (used as control), respectively. The body weight, food consumption, reproductive parameters, hematological parameters, serum chemistry, organ weight, and histopathology for the three generations were examined, respectively. Minor differences were found between the GM group and the RM group or the AIN control group in terms of reproductive data, hematology, blood chemistry parameters, and organ index, but no macroscopic or histological adverse effects were found or considered as treatment-related. In conclusion, the three-generation study of genetically modified maize DBN9936 with Cry1Ab and epsps genes at a high level showed no unintended adverse effects on rats' reproductive system.

Abstract
OBJECTIVE To evaluate the effects of genetically modified maize with Cry1Ab and epsps genes on immune function in F3 rats. METHODS A total of 180 weaning SD rats for F0 generation were randomly divided into three groups, which were treated with AIN-93 G feed control diet, parental maize diet and genetically modified maize diet respectively. After three generations of breeding, antibody producing cells determination, concanavalin A(ConA)-induced lymphocyte transformation test, natural killer(NK)cells activities assay, whole blood lymphocyte subtype detection, delayed type hypersensitivity test and immunity organ index were performed. RESULTS There were no significant differences between parental maize diet and genetically modified maize diet in terms of the number of antibody-producing cells, ConA-induced spleen lymphocyte proliferation, NK cell activity, whole blood lymphocyte subsets, delayed type hypersensitivity and thymus index(P>0. 05). CONCLUSION Under the conditions of this experiment, no significant effects were found on immune function of F3 SD rats through the three generation development study of genetically modified maize with CrylAb and epsps genes.

Abstract
1. Fatty acid-binding proteins (FABP) are members of lipid-binding proteins, which participate in the metabolism and intracellular transportation of lipids. This study was designed to investigate the expression patterns, polymorphisms and associations with meat quality traits of the FABP1 gene in pigeons. 2. The temporal-spatial expression patterns showed FABP1 was widely expressed in all eleven tissues from 0-4 weeks of age, the expression level in the liver was the highest, followed by the small intestine and subcutaneous fat. 3. Five novel SNPs were found; all of them were synonymous and in Hardy-Weinberg equilibrium. Association analysis revealed that for the SNP of G161C, the AB and BB genotypes had higher (P ≤ 0.01) inosinic acid concentrations in breast muscle than the AA genotype. The BB genotype showed the highest (P < 0.01) intramuscular fat among the three genotypes, and significantly greater FABP1 mRNA levels were observed in the breast muscle of the BB genotype than in the AA and AB genotypes (P < 0.01). In the SNP C1376T, the AB and BB genotypes showed higher (P < 0.01) intramuscular fat than the AA genotype, and the relative mRNA expression level of the BB (P < 0.01) and AB (P < 0.05) genotypes was higher than that of the AA genotype in breast muscle. Correlation analysis implied that the FABP1 mRNA expression level was closely related to the inosinic acid (P < 0.05) and intramuscular fat content (P < 0.01). Oil red O staining of frozen sections of breast muscle on d 28 for SNPs G161C and C1376T also indicated that the BB genotype had the highest intramuscular fat content in both SNPs. In addition, correlation analysis implied the FABP1 mRNA expression level was closely related to inosinic acid (P < 0.05) and intramuscular fat content (P < 0.01). 4. The results suggested that FABP1 could be a potential candidate gene in marker-assisted selection for breeding pigeons with high-quality meat.

Abstract
MLN4924, also known as pevonedistat, is a highly selective small-molecule inhibitor of NEDD8 (neuronal precursor cell-expressed developmentally downregulated protein 8)-activating enzyme (NAE) to block the entire neddylation modification cascade, leading to inactivation of cullin-RING ligases (CRLs), since activation of CRLs requires cullin neddylation. MLN4924 showed impressive anticancer activity in many preclinical studies and is currently in several Phase I/II clinical trials for anticancer therapy as a single agent or in combination with chemotherapeutic drugs.In addition to well-characterized anti-neddylation activity, recent studies showed that MLN4924 has several neddylation-independent activities. First, MLN4924 triggers EGFR dimerization to activate EGFR and its downstream RAS/MAPK and PI3K/AKT1 signals, leading to enhanced tumor sphere formation, accelerated EGF-mediated wound healing, and inhibited ciliogenesis. Second, MLN4924 induces PKM2 tetramerization to promote glycolysis, thus affecting energy metabolism. Third, MLN4924 inhibits the interaction between ACT1 (NF-κB activator 1) and TRAF6 (tumor necrosis factor receptor-associated factor 6) and attenuates IL-17A-mediated activation of NF-κB to reduce pulmonary inflammation. Fourth, MLN4924 inhibits IRF3 binding to the IFN-β promoter to inhibit IFN-β production. And finally, MLN4924 activates the JNK signaling pathway to reduce c-FLIP levels, thus enhancing TRAIL-induced apoptosis. This chapter will summarize these neddylation-independent activities of MLN4924 and discuss the underlying mechanisms and potential therapeutic applications.

Abstract
Magnetic resonance (MR) simulators have recently gained popularity; it avoids the unnecessary radiation exposure associated with Computed Tomography (CT) when used for radiation therapy planning. We propose a method for pseudo CT estimation from MR images based on joint dictionary learning. Patient-specific anatomical features were extracted from the aligned training images and adopted as signatures for each voxel. The most relevant and informative features were identified to train the joint dictionary learning-based model. The well-trained dictionary was used to predict the pseudo CT of a new patient. This prediction technique was validated with a clinical study of 12 patients with MR and CT images of the brain. The mean absolute error (MAE), peak signal-to-noise ratio (PSNR), normalized cross correlation (NCC) indexes were used to quantify the prediction accuracy. We compared our proposed method with a state-of-the-art dictionary learning method. Overall our proposed method significantly improves the prediction accuracy over the state-of-the-art dictionary learning method. We have investigated a novel joint dictionary Iearning- based approach to predict CT images from routine MRIs and demonstrated its reliability. This CT prediction technique could be a useful tool for MRI-based radiation treatment planning or attenuation correction for quantifying PET images for PET/MR imaging.

Abstract
Ten indigenous chicken breeds were originally distributed in Jiangxi Province, China, and they define a critical component of Chinese chicken genetic resources. We have investigated the population genetics of seven Jiangxi chicken breeds using 600K chicken BeadChip SNP data. To provide a genome-wide perspective for the population structure of all 10 Jiangxi chicken breeds, we herein genotyped 78 additional individuals from the seven breeds and 63 chickens from three uninvestigated breeds-Yugan Black (YG), Nancheng Black (NC) and Wanzai Yellow using 55K chicken SNP arrays. We then explored merged data of 17 101 SNPs from 235 individuals to infer the population structure of the 10 breeds. We showed that NC and YG are two regional populations of the same breed, as individuals from the two populations clustered together to form a branch separate from the other breeds in the neighbor-joining tree, they always grouped together in multidimensional principal component analyses and they displayed an identical pattern of ancestral lineage composition. Hence, NC and YG should be considered a single breed in the state-supported conservation scheme. Moreover, we conducted a genome scan for signatures of selection for black plumage. bayescan and hapflk analyses of two contrasting groups (three black-feathered breeds vs. six non-black-feathered breeds) consistently detected 25 putative regions under selection. Nine pigmentation- associated genes (DCT, SLC24A5, SLC30A4, MYO5A, CYP19A1, NADK2, SLC45A2, GNAQ and DCP2) reside within these regions, and these genes are interesting candidates for black plumage and provide a starting point for further identification of causative mutations for black feathers in chicken.

Abstract
OBJECTIVE To investigate the association between serum leptin concentration with blood pressure and hypertension in different gender. METHODS A total of 343 non-hypertensive residents aged 30 to 65 were randomly selected from Zhejiang Province in 2014. Parameters including height, weight, waist, blood pressure, serum lipid and serum leptin concentration of participants were measured and determined by physical examination and laboratory detection in 2014 and 2017. The differences in serum leptin levels between the new hypertensive and non-hypertensive people were compared after three years. The relationship between serum leptin levels and hypertension was analyzed by Logistic regression. RESULTS In 2014 and 2017, concentration of serum leptin in females was significantly higher than that in males, and the blood pressure in males was higher than that in females. At the end of follow-up, 26 new cases of hypertension were found. Serum leptin levels were higher in the female hypertensive group than in the non-hypertensive group(P=0. 0289), whereas there was no statistical difference in males(P>0. 01). Regardless of gender, serum leptin was significantly positively correlated with body mass index(BMI) and waist-to-height ratio(WHtR)(P<0. 0001), and also had correlation with blood pressure. However, after adjusting for BMI or WHtR, the correlation between serum leptin and blood pressure disappeared(P>0. 01). Logistic regression also showed the similar result. CONCLUSION Serum leptin is not directly related to blood pressure and hypertension, and the positive correlation between them may be explained largely by BMI and WHtR.

Abstract
BACKGROUND AND PURPOSE Significant clinical recovery has commonly been observed in ischaemic stroke patients with irreversible brain structural damage. However, brain mechanisms that help to maintain clinical function remain unclear. METHODS Sixty-two patients with acute ischaemic stroke underwent longitudinal clinical assessments and magnetic resonance scanning. The clinical recovery trajectory was evaluated using a hierarchical linear model and intrinsic connectivity was analysed with a seed-based approach to examine its changing pattern based on the regional volume changes calculated using voxel-wise analysis. RESULTS It was observed that clinical outcome measures improved mainly in the short-term period (baseline versus 3 weeks) and then remained stable. Grey matter volume was reduced significantly in the bilateral caudate over the entire 3-year long-term period. Significant intrinsic connectivity increases were observed in the caudate-middle cingulum over the short-term period and in the caudate-precuneus and caudate-calcarine over the long-term period. Finally, it was found that increased caudate-calcarine connectivity was associated with reduced right caudate volume, and a positive correlation was found between increased caudate-middle cingulum connectivity and the amount of modified Rankin score changes. CONCLUSIONS The increased intrinsic connectivity found in this study tends to be a compensatory mechanism for post-stroke structural damage, associated with clinical recovery. The study helps in understanding the significance of enhanced intrinsic connectivity in post-stroke long-term assessment and rehabilitation.

Abstract
Jiangxi province in China is rich in indigenous chicken breeds, which have diverse phenotypes and represent a valuable genetic resource for further genetic improvement of modern breeds. Here, we conducted a series of analyses to reveal genetic diversity, phylogenetic relationships and population structure of seven chicken breeds in Jiangxi province in the context of nine non-local chicken breeds, using 600K SNP data. We show that Jiangxi indigenous breeds have more abundant nucleotide diversity than do European local and commercial breeds. Among Jiangxi breeds, Dongxiang Blue-eggshell (DX) and Chongren Partride (CR) display remarkably reduced genetic diversity, as the two breeds exhibit increased inbreeding coefficients, runs of homozygosity, extent of linkage disequilibrium and reduced expected heterozygosity. DX, CR and Taihe Silkie (TH) represent three ancestral lineages of the Jiangxi chicken and display genetic differentiation from the other four Jiangxi breeds, which show a signature of admixture with European commercial breeds. These findings provide insight for the establishment of an efficient conservation program for Jiangxi chicken breeds. Considering the current status of genetic diversity and ancestral representativeness, particular attention should be paid to DX, CR and TH chickens.

Abstract
The Src homology and collagen A (ShcA) adaptor protein that binds to tyrosine kinase receptors. ShcA plays a role in insulin signaling, stress resistance and energy metabolism. The 66-kDa Src homology 2 domain-containing protein (p66shc) belongs to the ShcA family and has been associated with reactive oxygen species (ROS); increased ROS is involved in the pathology of lupus nephritis (LN). However, whether ShcA can act as a biomarker for oxidative injury in LN is unknown. This study is aimed to investigate the ShcA expression in kidney tissues from patients presenting with LN and the association between ShcA expression and clinical parameters. Renal biopsy tissues were obtained from 62 LN, 20 primary membranous nephropathy (MN) and 10 other secondary MN patients. ShcA was measured by immunofluorescence. The expression of ShcA in the membranous lupus nephritis (class V) group showed a higher trend but there were no significant differences compared with pure mesangial disease (class II) and proliferative (Class III/IV) lupus nephritis. ShcA deposits were negative in primary and other secondary MN. ShcA might act as a new biomarker and a diagnostic tool to identify membranous lupus nephritis with other MN.

Abstract
It is unclear whether combat eyewear used by U. S. Service members is protective against blast overpressures (BOPs) caused by explosive devices. Here, we investigated the mechanisms by which BOP bypasses eyewear and increases eye surface pressure. We performed experiments and developed three-dimensional (3D) finite element (FE) models of a head form (HF) equipped with an advanced combat helmet (ACH) and with no eyewear, spectacles, or goggles in a shock tube at three BOPs and five head orientations relative to the blast wave. Overall, we observed good agreement between experimental and computational results, with average discrepancies in impulse and peak-pressure values of less than 15% over 90 comparisons. In the absence of eyewear and depending on the head orientation, we identified three mechanisms that contributed to pressure loading on the eyes. Eyewear was most effective at 0 deg orientation, with pressure attenuation ranging from 50 (spectacles) to 80% (goggles) of the peak pressures observed in the no-eyewear configuration. Spectacles and goggles were considerably less effective when we rotated the HF in the counter-clockwise direction around the superior-inferior axis of the head. Surprisingly, at certain orientations, spectacles yielded higher maximum pressures (80%) and goggles yielded larger impulses (150%) than those observed without eyewear. The findings from this study will aid in the design of eyewear that provides better protection against BOP.

Abstract
OBJECTIVE To evaluate the neurotoxicity effects of the genetically modified maize with insect-resistant Cry1 Ab and herbicide-resistant epsps genes on the SD rats through three generation exposure. METHODS 180 weaning SD rats for F0 generation were divided into three groups, which were treated with parental maize diet( YC group), genetically modified maize diet( T group) and AIN-93 G control diet( C group). After three generations of breeding, 20 litters of rats those from pre-weaning F3 generation were selected randomly to evaluate early postnatal developmental neurotoxicity. After weaning, 10 pups were randomly selected from each litter( 1 male or female per litter) for future experiments of motor activity, cognitive function and neuropathology assessment as adult. RESULTS There were no statistically significant differences on early neurological development, neuroethology and cognitive ability. Only in the spatial probe test, the distance and time spent as well as their corresponding percentage in the target quadrant of YC group female rats were less compared with T group and C group( P < 0. 05). CONCLUSION Under current experimental conditions, no adverse effects were found in neuroethology and cognitive ability on SD rats though the three generation study of genetically modified maize with Cry1Ab and epsps genes.

Abstract
Background Transcatheter aortic valve replacement (TAVR) is widely applied for the treatment of severe aortic stenosis (AS) in developed countries; however, in China, it is still in the early stage of utilization. On the basis of previous studies, this work explored the feasibility of TAVR in patients with severe AS in China and analyzed the cause of death in four cases. Methods This retrospective study included 20 patients who had severe AS and underwent TAVR with a balloon-expandable system (Edwards SAPIEN XT) in our hospital from January 2011 to June 2016. The valve and heart functions of 16 survivors before and after the TAVR procedure were compared. TAVR endpoints, device success, and adverse events were assessed according to the definitions of the Valve Academic Research Consortium-2 (VARC-2). Results There were 13 male and seven female patients aged 65–81 years (average, 73.15) who underwent TAVR. The TAVR approach was transfemoral in 19 patients and transapical in one patient. Four patients died (two of coronary artery occlusion and two of aortic annulus rupture) during the TAVR procedure or shortly after; six patients had mild paravalvular leakage, and the rest of the patients showed a significant improvement in cardiac function. During the follow-up period (2–62 months), one patient died of lung cancer 13 months after the TAVR procedure. Conclusion TAVR with a balloon-expandable system is safe and effective and can be used for patients with severe AS in China. It requires careful patient selection and preoperative assessment so as to reduce the 30-day postoperative mortality rate.

Abstract
Colon cancer is one of the most common digestive tumors. The present study aimed to explore the functional role, as well as the underlying mechanism of long non-coding RNA LINC00261 in colon cancer. Expression of LINC00261 was analyzed in colon cancer cell lines and human normal cell lines. Acquired resistance cell lines were then built and the acquired resistance efficiency was detected by evaluating cell viability. Thereafter, the effects of LINC00261 overexpression on cisplatin-resistant colon cancer cells were measured, as well as cell apoptosis, viability, migration, and invasion. Subsequently, we investigated the interaction of LINC00261 and β-catenin. The results showed that the LINC00261 gene was down-regulated in colon cancer cell lines and tissues, and in cisplatin-resistant cells. LINC00261 overexpression might relieve cisplatin resistance of colon cancer cells via promoting cell apoptosis, and inhibiting cell viability, migration, and invasion. Moreover, LINC00261 might down-regulate nuclear β-catenin through restraining β-catenin from cytoplasm into nuclei or it could also promote β-catenin degradation and inhibit activation of Wnt pathway. Finally, LINC00261 reduced cisplatin resistance of colon cancer in vivo and enhanced the anti-colon cancer effect of cisplatin through reducing tumor volume and weight.

Abstract
A systematic study was conducted to identify reliable reference genes for normalization of gene expression analysis in the blotched snakehead Channa maculata under normal physiological conditions. Firstly, the partial complementary (c)DNA of nine candidate reference genes (actb, tmem104, ube2l3, ef1α, churc1, tmem256, rpl13a, sep15 and g6pd) were cloned from C. maculata. The expression levels of these genes were then assessed in embryos of different developmental stages and various tissue types of adult fish using quantitative real-time (qrt-)PCR. RefFinder algorithm was used to evaluate the expression stability of these genes based on their cycle-threshold (Ct ) values in the qrt-PCR analysis. Results showed that there was no single best reference gene for all stages of embryos and adult tissues tested. Furthermore, it was found that, among the nine candidate genes tested, actb and tmem104 were the most stable reference genes across adult tissue types, while sep15 and tmem256 were the most stable ones across developmental stages of embryos. These stable reference genes are recommended for normalization of gene expression analysis in C. maculata.

Abstract
OBJECTIVE To investigate the effects of isocaloric diets with different percentage energy from fat on blood glucose and lipids in rats. METHODS Forty male SD rats were assigned to low fat group, normal fat group, medium fat group and high fat group using randomized blocks method. Rats in four groups were fed with isocaloric diets whose percentage energy from fat were 5%, 15%, 25% and 40% respectively for 10 weeks. Body weight and body length of rats were measured every week. Blood glucose, blood lipids and insulin were determined at 0, 5th and 10 th week. The perirenal fat and epididymal fat pad were separated and weighed at the end of the 10 th week and the body fat rate was calculated. RESULTS At the end of the 5th and 10 th week, there were no significant differences among four groups in body weight, Lee's index, body fat rate, insulin and low density lipoprotein cholesterol. At the end of the 10 th week, the level of blood glucose was higher for rats in the high fat group than those in the low fat group( P <0. 01). The level of total cholesterol, triglyceride and high density lipoprotein cholesterol were lower for rats in the high fat group than those in the low fat group( P < 0. 01). The level of blood glucose of the 10 th week was higher for rats in the high fat group than the level at the beginning( P < 0. 05). The level of total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol of the 10 th week was higher for rats in the high fat group than the level at the beginning( P < 0. 01). CONCLUSION When rats were fed with a isocaloric diet and in the condition of normal growth, diet with high proportion of energy derived from fat would not lead to overweight in rats, whereas it may change the metabolism of blood glucose and lipids.
